Cimetidine is primarily used to treat the following conditions:
Heartburn: Cimetidine can provide relief from heartburn, a burning sensation in the chest caused by stomach acid flowing back into the esophagus.
Gastric Ulcers: It is used to treat gastric ulcers, which are open sores that develop on the lining of the stomach.
Duodenal Ulcers: Cimetidine is also effective in treating duodenal ulcers, which are ulcers that develop in the first part of the small intestine.
Gastroesophageal Reflux Disease (GERD): Cimetidine can help manage GERD, a chronic condition where stomach acid frequently flows into the esophagus, leading to symptoms such as heartburn and regurgitation.
Zollinger-Ellison Syndrome: In rare cases, cimetidine may be prescribed to manage excessive stomach acid production associated with Zollinger-Ellison syndrome, a rare tumor condition.
